Fabrication of Enzyme-Loaded Cartridges Using CO2-Assisted Polymer Compression

Abstract

An enzyme-loaded disk-shaped cartridge was fabricated using CO2-assisted polymer compression (CAPC), which is a polymer-bonding method that does not use heat. In this process, after the enzyme was loaded onto mesoporous silica, it was placed in a container fabricated from laminated fibrous sheets using CAPC. Subsequently, the lid and container were bonded via CAPC. Verification using the reductive decomposition reaction of an azo dye (methyl red) showed that the enzyme was not deactivated and that a reaction cartridge was created successfully.
